Hi everyone,
This is another of my novice questions relating to VCA or mixer attenuation/muting so apologies in advance.
Does the number of signals packed into an amount of space in a module/on a PCB potentially have an effect on the amount of bleed/cross-talk between signal paths/channels? I suppose it’s not as simple as that because it would depend on how the boards are designed and the quality of the components, ICs etc. but generally speaking is it harder to isolate channels if there are more of them packed into a small space? I would think so based purely on EM principles but I’m not sure if/how this manifests itself in euro synth modules.
An example would be say the Doepfer A-135-5 polyphonic mixer which contains 12 VCAs (basically it is for mixing up to 3 sound sources per voice (4 voices)). https://doepfer.de/a1355.htm
How well can one reasonably expect those 3 channels within each voice to be isolated, or how well can one reasonably expect each of the 4 voices to be isolated vs a hypothetical version of this module which was 2 or 3 times the hp, or vs racking 4 separate 3-channel VCA/mixer modules all other things being equal?
It’s not so much the audio “quality” I’m thinking about but more the “leakage” across all these VCAs. For example if one had a module such as that Doepfer fully patched and then muted A or B or C. That sort of thing.
